###############################################################################
MIG outputs script files required to run the simulations for Modelsim/QuestaSim,
Vivado Simulator, IES and VCS. These scripts are valid only for running
simulations for "Open IP Example Design"
1. How to run simulations in Modelsim/QuestaSim simulator
A) sim.do File :
a) The 'sim.do' file has commands to compile and simulate memory
interface design and run the simulation for specified period of time.
b) It has the syntax to Map the required libraries (unisims_ver,
unisim and secureip). The libraries should be mapped using
the following command
vmap unisims_ver <unisims_ver lib path>
vmap unisim <unisim lib path>
vmap secureip <secureip lib path>
Also, $XILINX_VIVADO environment variable must be set in order to compile glbl.v file
c) Displays the waveforms that are listed with "add wave" command.
B) Steps to run the Modelsim/QuestaSim simulation:
a) The user should invoke the Modelsim/QuestaSim simulator GUI.
b) Change the present working directory path to the sim folder.
In Transcript window, at Modelsim/QuestaSim prompt, type the following
command to change directory path.
cd <sim directory path>
c) Run the simulation using sim.do file.
At Modelsim/QuestaSim prompt, type the following command:
do sim.do
d) To exit simulation, type the following command at Modelsim/QuestaSim
prompt:
quit -f
e) Verify the transcript file for the memory transactions.
2. How to run simulations in Vivado simulator
A) Following files are provided :
a) The 'xsim_run.bat' is the executable file for Vivado simulator under
MicroSoft Windows environment.
b) The 'xsim_run.sh' is the executable file for Vivado simulator under
Linux environment.
c) The 'xsim_run.bat'/'xsim_run.sh' file has commands to compile and
simulate memory interface design and run the simulation for specified
period of time.
d) xsim_options.tcl file has commands to add waveforms and simulation
period.
e) xsim_files.prj file has list of rtl files for simulating the design.
f) $XILINX_VIVADO environment variable must be set in order to compile
glbl.v file
B) Steps to run the Vivado Simulator simulation:
a) Change the present working directory path to the sim folder of "Open
IP Example Design" path in the OS terminal.
b) Run the simulation using xsim_run.sh file under Linux environment and
xsim_run.bat under MicroSoft Windows environment.
c) Verify the transcript file for the memory transactions.
3. How to run Cadence IES Simulations
A) ies_run.sh File :
a) The "ies_run.sh" file contains the commands for simulation of the
hdl files.
b) Libraries must be mapped before running simulations. Following
procedure must be followed to before running simulations
1. Create two files named cds.lib and hdl.var in this directory
2. Create a directory 'worklib' in same directory.
mkdir worklib
3. Add following lines in the cds.lib file to map Xilinx libraries
DEFINE unisim /proj/xbuilds/2014.4_daily_latest/clibs/ius/13.20.005/lin64/lib/./unisim
DEFINE unisims_ver /proj/xbuilds/2014.4_daily_latest/clibs/ius/13.20.005/lin64/lib/./unisims_ver
DEFINE secureip /proj/xbuilds/2014.4_daily_latest/clibs/ius/13.20.005/lin64/lib/./secureip
DEFINE worklib ./worklib
4. ATTENTION: In above lines replace the path for libraries as per your
compiled Xilinx libraries directory
5. ATTENTION: Add the lines in the same order given above
6. Please make sure you need to map all Xilinx libraries mentioned above
7. Save and close the cds.lib file
Also, $XILINX_VIVADO environment variable must be set in order to
compile glbl.v file and the above mentioned library files
B) Steps to run the IES simulation:
a) Change the present working directory path to the sim folder of "Open
IP Example Design" path in the OS terminal.
b) Run the simulation using ies_run.sh file. Type the following command:
./ies_run.sh
c) Verify the ies_sim.log file for the memory transactions.
4. How to run Synopsys VCS Simulations
A) vcs_run.sh File :
a) The "vcs_run.sh" file contains the commands for simulation of hdl files.
b) Libraries must be mapped before running simulations. Following
procedure must be followed to before running simulations
1. Create a file named synopsys_sim.setup in this directory
2. Add following lines in the synopsys_sim.setup file to map Xilinx
libraries
unisim : /proj/xbuilds/2014.4_daily_latest/clibs/vcs/I-2014.03/lin64/lib/unisim
secureip : /proj/xbuilds/2014.4_daily_latest/clibs/vcs/I-2014.03/lin64/lib/secureip
unisims_ver : /proj/xbuilds/2014.4_daily_latest/clibs/vcs/I-2014.03/lin64/lib/unisims_ver
3. ATTENTION: In above lines replace the path for libraries as per your
Compiled Xilinx libraries directory
4. Please make sure you need to map all Xilinx libraries mentioned above
Also, $XILINX_VIVADO environment variable must be set in order to
compile glbl.v file and the above mentioned library files
B) Steps to run the VCS simulation:
a) Change the present working directory path to the sim folder of "Open
IP Example Design" path in the OS terminal.
b) Run the simulation using vcs_run.sh file. Type the following command:
./vcs_run.sh
c) Verify the vcs_sim.log file for the memory transactions.
5. SIM_BYPASS_INIT_CAL parameter value of SKIP, skips memory initialization sequence
and calibration sequence. This could lead to simulation errors since design is not
calibrated at all. Preferred values for parameter SIM_BYPASS_INIT_CAL to run
simulations are FAST and OFF.
